Question About T5ho Tek Light.

[cathyg_99]

all i can add to this is i have a 4ft 6 bulb t5 with the acrylic cover on it, they do get warm and it does raise my tank by 1C but i also have it as low as possible, they are still cooler than the coralife ones i used to have

I find the lens sags with the heat but no problems otherwise.
